Hey

You can use an original WALBRO pump, they are about $160 delivered from SLIDE in the for sale trader section.

BOSCH 040 I believe is the one your chasing, that is also a good option.

Personally would go for an original WALBRO as they are very reliable pumps. Few people pushing 300rwkw with them, as well as being very easy to install!

Its been covered heaps on the forums. Check the DIY/tutorial section and you will find and installation guide more than likely, also search the forced induction section for like "what fuel pump" and you should get a lot of results.

Good luck.

You can use either, the 040 has a filter built in and has to be mounted low, the 044 uses the standard sock filter and hose. If your r33 is stock you don't need either, if it's making 220rwkW - 280rwkW use the 040, if it's making 280rwkW - 400rwkW use 044.

Dont skimp on you fuel pump choice,go Nismo or Tomei,they are direct fit,and will easily cater to your power goal.

atm i'm making 180atw

but aimming for around 220-240

so i guess the walbro would be ok for this target?

cheers guys

yes it will be ok for that target but not much more

if your dead set you dont want no more than get the walbro/040 but MAKE SURE you dont want to go more because you will end up buying twice like alot of people

if i were to do it again, id spend the extra $250 and get a nismo/tomei from the start (ill have to do this when i change the turbo)

Dont skimp on you fuel pump choice,go Nismo or Tomei,they are direct fit,and will easily cater to your power goal.

TOMEI or a NISMO?

Man if you got the cash to spend $500 on a fuel pump then go ahead.. but a WALBRO pump for $160 delivered will serve you the EXACT same purpose.

There is a guy with an R33 which is running 300rwkw on a WALBRO pump.

theres been alot of people that have had problems with walbros running lean as they get higher up

sure they should handle up to about 300kw but usually they dont

i have one and its fine but im only running 200kw..

anyhow its just what i have read from others exprience so dont take my word for it

there is a fuel pump control module (FPCM) which regulates between a low and high volume mode, other then that it just pumps either of the 2 modes, that being said in your engine bay is a fuel pressure regulator (FPR) which regulates the pressure of the flow into the fuel rail meaning that the pump just pumps at its one speed all the time and the FPR regulate it for you.

that why these guys are saying it doesn't matter which pump you go far, if the WALBRO is leaning out up top its because it pumping at maximum pressure / volume and simply cannot supply more fuel.

the FPR cannot up the pressure provided by the fuel pump merely reduce and regulate it

Would there be any problem with running a Tomei pump on a stock (with turbo back exhaust) R33 GTST. Would it run unnecessarily rich or does it only pump what is required?

You wont have any problem at all, it'll run fine (fuel reg will regulate pressure).

After much research and pondering what pump I should install (040, 044, Walbro 255, Tomei kit etc) I came to the conclusion that the Tomei kit (has everything you need including new seal, clamps, harness, wiring etc) is well worth the $360 advertised in the classifieds of this forum. It was a easy direct install with no modifications.

  • 8 months later...
I've just bought a new Walbro fuel pump from Slide, should be here on Monday.

I opted for the Walbro because I'm only aiming for around 200rwkw.

hey just wondering that walbro fuel pump that you got is that from the trading post

    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
